Mammogram

Guide

A mammogram is an X-ray of the breast that is used to screen for breast cancer. Mammograms can find tumors that are too small for you or your doctor
to feel.

Cancer
is most easily treated and cured when it is discovered in an early stage. Mammograms do not prevent breast cancer or reduce a woman's risk of developing
cancer. But for women ages 40 to 74, mammograms can help reduce deaths from breast
cancer.1

Your doctor may recommend testing at a younger age if you have risk factors for breast cancer.

Breast Cancer Screening: When Should I Start Having Mammograms?

A mammogram that appears to detect a cancer, when in fact a
cancer is not present (false-positive results), can occur at
any age but is more likely to occur in younger women. About 5% to 10% of
screening mammograms will require more testing. This may include another
mammogram of specific breast tissue or another test, such as
an
ultrasound. Most of these tests will show no cancer is
present.
